Find it! Searching Databases - Hands-on workshop Chemistry Research Project (CHE600) School of Biological and Chemical Sciences

Can you remember what we did last session? NOV Go to and use the code

Learning Objectives By the end of this session you should be able to:  Understand the principles of literature searching  Use Web of Science and Reaxys to carry out searches and refine and sort your results in order to identify the most relevant citations  Use the citation network to expand your search NOV

INTRODUCTION TO DATABASES

Databases: What are they? NOV 2015  Searchable indexes of evaluated literature such as journal articles and conference proceedings  Types of database:  Bibliographic indexing & abstracting databases or full-text collections  Subject-specific or interdisciplinary  Use to carry out literature searches

NOV 2015  Major search tool comprised of 3 indexes that provide multidisciplinary coverage of academic literature (Science Citation Index, Social Sciences Citation Index, Arts & Humanities Citation Index). The Science Citation Index covers almost 7000 journals from 1952 onwards. Web of Science was formerly known as Web of Knowledge

SEARCH TECHNIQUES

Keywords  Develop an effective search strategy:  Identify the key concepts in your topic  Choose keywords relating to each concept  Think about acronyms, alternative spellings (e.g. US or UK), synonyms and related terms NOV

Wildcards  Use wildcards (*, ?, $) for word variations, e.g.  singular / plural, nouns / verbs, UK / US spellings  The asterisk (*) represents any group of characters, including no character  The question mark (?) represents any single character  The dollar sign ($) represents zero or one character NOV

Wildcards  Wildcard examples:  microscop*finds microscope, microscopic, microscopy, etc.  polymeri?ation finds both polymerisation and polymerization  colo$rfinds both colour and color NOV

Phrase Searching  To search for an exact phrase, enclose the words in quotation marks, for example “chemical synthesis of carbon”  Searching for chemical synthesis of carbon without quotation marks would retrieve citations with these keywords anywhere within the field searched NOV

NOV

Boolean Operators NOV 2015 AND Search for articles that contain both of the search terms. Using AND narrows your search OR Search for articles that contain one or both of the search terms (useful for synonyms). Using OR broadens your search NOT Search for articles that contain the first term and do not contain the second term. Using NOT narrows your search

Curie AND Chemistry NOV 2015 Boolean Search String Game Pierre Curie: A Life Cut Short Marie Curie : Heroine of Chemistry Radioactive: The science of Curie Chemistry OR Science Curie NOT U-boat 14

Boolean Operators  Use parentheses to group compound Boolean operators, for example:  Correct: (galvanic OR voltaic) AND cell  Incorrect: galvanic OR voltaic AND cell  Database search fields sometimes fulfil the same function as sets of parentheses NOV

Refine and Sort Your Search  Refine (narrow) your results by:  searching within results  limiting to subject areas  limiting by publication date  limiting by document format  Sort your results by:  relevance  times cited  publication date NOV

SEARCHING WEB OF SCIENCE

Accessing Web Of Science  You can access Web of Science via a Library Catalogue search or the Library’s subject support webpages for Chemistry: NOV

SEARCHING REAXYS

Reaxys NOV 2015 Provides access to Beilstein (organic) Gmelin (inorganic) and patent chemistry databases. It covers over 200 years of primary literature and contains data on structures, reactions, facts and citations for more than 11 million organic, inorganic and organometallic compounds.

TWO EXERCISES

Exercise 1 Van Zeist, W.-J. & Bickelhaupt, F.M., The activation strain model of chemical reactivity. Organic & biomolecular chemistry, 8(14), pp.3118–27. Use Web of Science to find this journal article and answer the following: 1)How many references are cited by the authors? 2)How many times has the article been cited? 3)Can you access the full text of this article? NOV

Exercise 1 Answers: 1)74 2)155 times [06/11/2015] 3)Yes, via RSC Journals NOV

Exercise 2 NOV 2015 You want to find journal articles about electrochromism resulting from electrochemical intercalation and have jotted down the following keywords: intercalation, insertion, electrochromic, electrochromism  Construct a search to retrieve relevant WoS citations  Points to consider:  What are the two main concepts? What are the synonyms or related terms?  Which word(s) might need to be truncated?
